INSIDE BLIND.

SPECIFICATION forming part of Letters Patent No. 355,168, dated December28, 1886.

Application filed December 28, 1885. Serial No. 186,916.

To all whom it may concern:

Be it known that I, WALTER A. HOL- BROOK, a citizen of the UnitedStates, residing at Milwaukee, in the county of Milwaukee and State ofWVisconsin, have invented certain new and useful Improvements in InsideBlinds; and I do declare the following to be a full,

' clear, and exact description of the invention,

such as will enable others skilled in the art to i which it appertainsto make and use the same, reference being had to the accompanyingdrawings, and to letters or figures of reference marked thereon, whichform a part of this specification.

Figure 1 of the drawings is a representation of a front elevation, oneside thereof being in vertical section. Fig. 2 is'a vertical centralsection of the same, and Fig. 3 is a horizontal transverse section.

This invention relates to inside shutters for windows; and it consistsin the construction and novel combination of parts, as will behereinafter described, and pointed out in the claim.

Referring by letter to the accompanying drawings, A designates thejamb-lining of a window-frame, which is provided with the integralparting-strips B, which, in connection with integral side guide-strips,G 0, form the guideways for the sliding blind-sections. Be

tween the side guide-strips, O G, and the parting-strips B, about midwayof the length of the window-frame, I provide single pulleys or groovedwheels G in one of the pairs of vertical grooves H, said grooves beingthe outside grooves, and in the inside grooves I provide wheels J J,placed in said grooves. The section D of the blind is the uppermost ofthe four sections, and is held in place by springs located in itsgrooved edges and secured in place by screws, which springs normallypress outwardly against the material of thewindowframes and hold thesection D of the sliding blind to any point to which it may have beenadjusted. Weighted cords M are provided for the lower blind-section, andthese cords M are run over the outside single pulleys or (No model.)

nying drawings, that various adjustments of i the sliding sections maybe made for the purpose of excluding or admitting light and air.

I is a molding to cover joints between jamb lining and window-frames,thereby dispensing with grooving window-frames to take tongue orjarnb-piece as'in the ordinary construction, and allowing the puttingtogether at the 'factory of the jamb-lining and casings, with the blindsections set in already to set up to the window-frame. 7

Section D, instead of. wood panel, may be filled in with stained-glass,the frame remaining as before. This gives the same effect fromthe-inside, and is much cheaper thanproviding frame outside for saidglass.

Having described this invention, what I claim, and desire to secure byLetters Patent, 7

The combination, with a window-frameconstructed as described andprovided with the sashways having the central vertical integralparting-strips and the outer guide-strips, of the pulleys arranged inthe said ways, the

counterbalancing-sections connected by ropes I WVALTER A. HOLBROOK.
